Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A charge of 1 C is in a magnetic field of 5 T moving at 10 m/s forms an angle of 30 degrees with the field. Calculate the magnetic force acting on the charge.

💡 Hint: Focus on evaluating the sine function correctly.

Challenge 2 Hard

If the electric field is 4 N/C and magnetic field is 2 T, what is the Lorentz force on a charge of -3 C moving at 3 m/s in the same direction as the electric field?

💡 Hint: Don’t forget to consider the charges' sign while calculating the force.
